This study was carried out to determine the effects of grazing on soil parameters in the meadow ecosystems in the alluvial delta plain of Samsun-Turkey. Five 5×5 m exclosures were established in the homogeneous stands in terms of habitat conditions and floristic composition in the study area during 2000-2003. The top of soil was firstly removed and then soil samples were taken from inside and outside of exclosures at a depth of 20 cm in each month for a year. Soil organic matter, pH, nitrogen, phosphorus, potassium, $CaCO_3$ and total salinity were measured by standard methods. In general, $CaCO_3$ and total salinity exhibited statistically significant differences between the grazed and ungrazed parts.
